Things like this happen. Only working until vimeo changes the way it gets the video files again.

vimeo_downloader.sh

#!/bin/sh
if [ $# -ne 2 ]; then
        echo "Usage: $0 vimeo_id filename"
        exit 1
fi

GET="wget -U '${USER_AGENT}' -q -O -"
# Get the json
JSON=`$GET http://vimeo.com/${1} |grep https://player.vimeo.com/video/${1}/config |perl -p -e 's/^.*e\.open\("GET","(https:\/\/player.vimeo.com\/video\/.+\/config.+?)".*$/$1/'`

URL=`$GET $JSON |perl -p -e 's/^.*"profile".*width":720.*?"url":"(.*?\?token.*?)".*$/$1/'`

# Get the video
$GET $URL > $2
